I'm not sure exactly what's wrong with your job, but we provide the
following STAX job: http://staf.sourceforge.net/current/getLatest.xml
which you may want to use as an example, since it does some similar
processing (for example it parses for multiple <file> elements).
Actually the DocumentBuilderFactory and related classes are Java classes
(not Jython), so searching on the web for the following should provide
some useful links.
javax.xml.parsers.DocumentBuilderFactory
javax.xml.parsers.DocumentBuilder
org.w3c.dom.Document
org.w3c.dom.Element
org.w3c.dom.Node
org.w3c.dom.NodeList
Thanks,

Subject
[staf-users] Parsing a xml file using document builder factory.
Hi ,
This is not really related to STAF and STAX , but would be a time saver .I
am quite new to jython xml parsing using document builder.
I am trying to read a xml file of the following format in the staf and
stax job xml file:
<?xml version="1.0" encoding="utf-8"?>
<operating_system>
<unix_80sp1>
<tests type="quick_sanity_test">
<prerequisitescript>preparequicksanityscript</prerequisitescript>
<acbuildpath>acbuildpath</acbuildpath>
<testsuitscript>test quick sanity script</testsuitscript>
<testdir>quick sanity dir</testdir>
</tests>
<machine_name>u80sp1_L004</machine_name>
<machine_name>u80sp1_L005</machine_name>
<machine_name>xyz.pxy.dxe.cde</machine_name>
<vmware id="155.35.3.55">144.35.3.90</vmware>
<vmware id="155.35.3.56">144.35.3.91</vmware>
</unix_80sp1>
</operating_system>
Here machine_name tag can be n number. I need to read all the machine_name
tags in an array , so that i can use them later.
Also i need to read all the vmware tags in an array (both value and
attributes) so that i can use them later. The number of vmware tags can
again be n numbers.
I am trying the following code :
<!-- *******************************************************************
-->
<!-- Following function is used to parse an XML file and return the DOM
-->
<!-- document object
-->
<!-- *******************************************************************
-->
<function name="parseXML" scope="local">
<function-list-args>
<function-required-arg name="xmlFileName">
Name of file containing XML to be parsed
</function-required-arg>
</function-list-args>
<sequence>
<!-- Parse the XML -->
<script>
factory = DocumentBuilderFactory.newInstance();
factory.setValidating(1)
factory.setIgnoringElementContentWhitespace(0)
builder = factory.newDocumentBuilder()
document = builder.parse(xmlFileName)
</script>
<script>
vmware = None
machine_name = None
# Get the text value for the element with tag name "vmware"
nodeList = document.getElementsByTagName("vmware")
for i in range(nodeList.getLength()):
node = nodeList.item(i)
if node.getNodeType() == Node.ELEMENT_NODE:
children = node.getChildNodes()
for j in range(children.getLength()):
thisChild = children.item(j)
if (thisChild.getNodeType() == Node.TEXT_NODE):
machine_name = thisChild.getNodeValue()
# Get the text value for the element with tag name "machine_name"
nodeList = document.getElementsByTagName("vmware")
for i in range(nodeList.getLength()):
node = nodeList.item(i)
if node.getNodeType() == Node.ELEMENT_NODE:
children = node.getChildNodes()
for j in range(children.getLength()):
thisChild = children.item(j)
if (thisChild.getNodeType() == Node.TEXT_NODE):
machine_name = thisChild.getNodeValue()
</script>
<return>[machine_name,vmware]</return>
</sequence>
</function>
I am able to read only one value for machine_name (u80sp1_L005) and also
one value for vmware
i.e 144.35.3.91.
Also a good link to understand parsing in jython using doumentbilder
factory would be good help.
Regards
Sangram
